Mr Cameron and wife Samantha watched a relay exchange take place on their
doorstep in Downing Street tonight as war hero Kate Nesbitt handed over the
flame to pensioner Florence Rowe.

Miss Nesbitt, 24, from Plymouth, Devon, was the first woman in the Royal Navy to be awarded the Military Cross.

She was given the award in honour of her bravery in administering emergency medical treatment to injured servicemen while under enemy fire during an ambush in Afghanistan in March 2009.

Miss Nesbitt met the Camerons on the steps of Number 10 and chatted to them briefly before she handed over the flame to Ms Rowe, 81, from Prestwood in Buckinghamshire, who carried the flame out of Downing Street.

Mr Cameron hailed her ''huge heroism'' on the battlefield and the medic afterwards said carrying the torch had been ''incredible''.
